In accordance with the general principles of Islamic Law, beef is essentially lawful. Allah says: “It is He who created for you all that is in the Earth.” [Sûrah al-Baqarah: 29]
Allah also says: “It is He who has put forth the Earth for His creatures.” [Sûrah al-Rahmân: 10]
The hadîth the questioner refers to is as follows:
It is related from Mulaykah bint `Umar that Allah’s Messenger (peace be upon him) said regarding the cow: “Its milk is a healing, its fat is a medicine, and its flesh is a disease.” [al-Baghawî]
It is also related from Ibn Mas`ûd that the Prophet (peace be upon him) said: “Use the milk and fat of the cow and avoid its flesh, for indeed its milk and fat are a medicine and its flesh is a disease.” [Mustadrak al-Hâkim]
This hadîth, which is used as evidence to support the opinion that beef consumption is disliked, is of disputed authenticity among scholars. The stronger view is that it is unauthentic.
This view is supported by the hadîth related by Jâbir that the Prophet (peace be upon him) slaughtered a cow on `A’ishah’s behalf on the Day of Sacrifice. [Sahîh Muslim (1319)]
It is also supported by the fact that `A’ishah said: “The Prophet (peace be upon him) sacrificed cows on behalf of his wives.” [Sahîh al-Bukhârî (5559) and Sahîh Muslim (1211)]
From this, it would seem apparent that, in Islamic Law, beef consumption is not disliked.
